Here's a look at the top offensive performers in each league for the week ending June 16:
Zach Walters, Syracuse
(.579/.600/1.211, 5 G, 11-for-19, 3 2B, 3 HR, 7 RBI, 4 R, 0 BB, 1 K)
A switch-hitting shortstop, Walters has struggled in his first full season in Triple-A. Despite being rated the Nationals' No. 14 prospect, the 23-year-old hit .202 in May and owns a .265 on-base percentage in 61 games. He does, however, have 14 home runs, three of which came this week. Walters delivered a solo shot and a double against Pawtucket on Tuesday and went deep twice against Toledo Friday night.

Pacific Coast League
Mike Jacobs, Reno
(.567/.594/1.067, 7 G, 17-for-30, 3 2B, 4 HR, 13 RBI, 9 R, 2 BB, 4 K)
The veteran Jacobs was a solid contributor to Reno's PCL championship campaign last season, mashing 18 homers and 60 RBIs in 101 games. After being cut by the Mariners in Spring Training, the 32-year-old slugger headed to Mexico to play for Oaxaca but recently rejoined the Aces when first baseman Kila Ka'aihue left the club. Jacobs has made an immediate impact for Reno, collecting 17 hits -- seven of them for extra bases -- last week. In his first 12 games since returning, Jacobs is hitting .438/.491/.813 with five home runs, 15 RBIs and 12 runs scored.
Caleb Joseph, Bowie
(.522/.538/.783, 6 G, 12-for-23, 3 2B, 0 3B, 1 HR, 7 RBI, 4 R, 2 BB, 2 K, 1 CS)
A seventh-round pick in 2008, Joseph's sixth pro season is turning out to be easily his finest at the plate. The backstop, who turns 27 on Tuesday, had never hit more than 12 home runs or batted over .285 in any campaign. This year he's hitting .305/.359/.549 and has already gone deep 13 times and driven in 50 runs. Though he only homered once last week, he posted five multi-hit games and now ranks second in the Eastern League in RBIs and fourth in slugging.
Baysox's Joseph homers off Neris
Trayce Thompson, Birmingham
(.435/.440/.826, 6 G, 10-for-23, 0 2B, 0 3B, 3 HR, 9 RBI, 5 R, 1 BB, 7 K, 2 SB, 1 CS)
Thompson's power and talent have never been in question, merely his ability to consistently put the ball in play -- over the last two seasons, the White Sox's No. 2 prospect has clubbed 49 home runs while striking out 238 times. Though his power numbers are down so far in 2013, so are his strikeouts, and his .367 on-base percentage is the highest of his career. The 22-year-old had hits in each of his six games last week, including a home run against Jacksonville on Tuesday and a pair of blasts and five RBIs as the Barons rallied to edge Jackson, 9-8, on Sunday.

Alex Buchholz, Frisco
(.478/.538/.826, 6 G, 11-for-23, 2 2B, 0 3B, 2 HR, 5 RBI, 5 R, 3 BB, 2 K)
Buchholz began the week in an 0-for-15 slump covering his previous four games, but broke out in a big way at Midland on Tuesday, going 4-for-4. The 25-year-old third baseman added three more hits the next day and closed out the week with a pair of solo homers over his final four games. Buchholz, a University of Delaware product, never hit more than eight home runs in any of his first five seasons; he has eight already this year (six in 43 games with Frisco and two more in 13 contests with Triple-A Round Rock).

Jon Garcia, Rancho Cucamonga
(.560/.577/1.160, 6 G, 14-for-25, 2 2B, 2 3B, 3 HR, 11 RBI, 5 R, 1 BB, 6 K, 3 SB)
After batting just .220 in May, Garcia is running wild in June with seven homers, 21 RBIs and a .443/.469/.934 line in 15 games. Having gone 5-for-6 last Sunday, the 21-year-old outfielder barely paused for breath the rest of the week. Garcia homered on Monday, went deep twice and drove in five runs Friday, added a second consecutive four-hit outing Saturday and tripled for the second straight contest on Sunday. Despite Garcia's offensive surge, the Quakes dropped six of seven games during the week and finished the first half of the season at 31-39.
Kyle Kubitza, Lynchburg
(.391/.563/1.043, 8 G, 9-for-23, 1 2B, 1 3B, 4 HR, 9 RBI, 6 R, 9 BB, 4 K, 1 CS)
Though Kubitza batted just .237 in May, he still reached base at a .398 clip thanks to 21 walks in 26 games. In June, the 22-year-old Texas State product has added hits to the mix to produce a .392/.508/.804 line. Last week, Kubitza included a dash of power, clubbing four homers over a five-day stretch to give him eight on the season. Kubitza now ranks third in the Carolina League with a .402 on-base percentage and fourth with a .507 slugging mark.

Florida State League
Javier Baez, Daytona
(.308/.438/1.231, 4 G, 4-for-13, 0 2B, 0 3B, 4 HR, 7 RBI, 4 R, 3 BB, 1 K; 2-for-4, 2 2B in All-Star Game)
In three of his four games last week, Baez went a combined 0-for-9. It was almost beside the point, however, as he packed a week's worth of offense into Daytona's 9-6 win over first-place Fort Myers Monday night, clubbing four homers and driving in seven runs. MLB.com's No. 15 prospect tied a Florida State League mark with the four blasts and later added a pair of doubles in the circuit's All-Star Game on Saturday night. The 20-year-old shortstop ranks fourth in the FSL in homers (13) and fifth in slugging (.548).

Chris Bostick, Beloit
(.458/.500/1.000, 7 G, 11-for-24, 1 2B, 0 3B, 4 HR, 14 RBI, 5 R, 2 BB, 4 K, 2 SB)
Bostick got hot at exactly the right time for the Snappers, going deep in back-to-back games Monday and Tuesday before collecting six hits and seven RBIs on Saturday and Sunday. Though the 20-year-old infielder homered twice on Saturday, he saved his very best for last: a two-out single in the ninth on Sunday delivered not only a walk-off 8-7 win over Clinton but also Beloit's first division title since 2007. A 44th-round pick out of Rochester, N.Y., in 2011, Bostick leads the Snappers in stolen bases and ranks second in home runs and RBIs.
South Atlantic League
Joey Gallo, Hickory
(.452/.500/1.226, 8 G, 14-for-31, 3 2B, 0 3B, 7 HR, 13 RBI, 11 R, 2 BB, 10 K)
The Crawdads are putting on a collective display of power this year that may be unprecedented in the South Atlantic League. At the heart of it are sluggers Gallo and Ryan Rua, who are tied for the Minor League lead with 22 home runs apiece. No one else in the Minors has more than 18, and nine teams in the Sally League cannot match their combined 44 blasts. While Rua went deep five times last week, Gallo bashed seven longballs, including a three-homer game at Hagerstown on Tuesday. Hickory is also posting impressive strikeout numbers -- Gallo's 108 are second only to Crawdads teammate Lewis Brinson's 109 in the Minors -- but 22 home runs in 68 games makes up for a lot of whiffing.
